Recent progress in the development of catalysts for propane dehydrogenation in the presence of CO2

Abstract

Propane dehydrogenation (PDH) has become an important strategy to address the ever-increasing global demand for propene. In this case, introducing CO2 as a soft oxidant for oxidative propane dehydrogenation (CO2-OPDH) not only promotes the reaction towards propene formation, but also expands the strategies for converting CO2 to valuable chemicals. Moreover, CO2 can also participate in the coke removal process to sustain the stability of catalysts. In this review, we present a comprehensive summary of the latest research progress in the synthesis strategies, reaction mechanisms and performances of catalysts, including supported metal oxides and noble metal catalysts. Furthermore, the nature of active sites, the critical role of CO2 in the intrinsic activity of catalysts and the evolution of active phases under reaction conditions are simultaneously discussed. Finally, the limitations of current catalysts and future perspectives in the field of CO2-OPDH are proposed. This review is expected to provide some guidance for the development of highly efficient catalyst design to facilitate the conversion of propane and carbon dioxide.
